Runtime errors usually occur due to unforeseen programming problems in applications that you might be using. These errors usually occur when certain conditions are true and were not actually detected and taken care of during the development of the application.
The error may occur when one of the following conditions is true:
- Your application is not installed properly or the installation files are corrupt.
- Certain required registry values are corrupt or missing.
- Template objects, such as Normal.dot and Excel.xlb are corrupt.
